Quite often it is necessary to air-condition spaces (very different
ones) where large supply air volume flows are concentrated into
small areas. In addition to this, there may be large distances from
the nozzles to the occupied zone.
In these cases jet nozzles can be used to solve the problem.
Being a multiple array of small units, these can be used to easily
replace a larger single jet nozzle.
Multi-jet nozzles are located in the side wall areas of the airconditioned space. When the temperature difference between
the supply air and the room air changes, the supply air stream
is deflected upwards (warm air) or downwards (cold air).
2
On the other hand, the direction of the supply air flow is also
affected by other influences such as local convention effects or
draughts within the space.
To deal with this situation, the TROX multi-jet nozzles can be
adjusted in any direction. The direction of the air stream from the
jet nozzle can be easily adjusted manually to suit particular site
conditions.
The well-designed, aerodynamically efficient shape of TROX jet
nozzles results in low noise characteristics. For this reason, and
because of the sophisticated design, they can be used in critical
areas such as concerts halls, theatres, museums etc.
Preliminary Selection
The table below gives a guide for selecting the size of a
multi-jet nozzle array.
The data shown is determined for an isothermal, single free
horizontal air stream.
According to our extensive experience, air velocities of 0.25 m/s
for example, with a throw of 30 m. are only possible in theory as
many room parameters must be taken into account with such
throw distances.
If the supply air temperature difference changes, the air stream
deflection in diagram 2, must be taken into account. The noise
levels are determined for the number of jet nozzles incorporated
into the multi-jet nozzle assembly.
In the table below no data is given for effective discharge velocities
below 2 m/s nor are values given above a sound power level
rating of 55 db(A). If the values required lie outside the limits of
this table then diagram 7 on page 14 should be used .

The basic jet nozzles can be one of three types, DUE-S-M, DUEV-M and DUE-F-M. The jet nozzles in the type DUE-S-M can be
manually adjusted angularly up to a maximum of 30ºup or down.
The type DUE-V-M can be in addition be manually rotated. The
type DUE-F-M has an array of fixed nozzles
The variations on these basic types are shown in the order codes
on page 15.
ØD1
The multi-jet nozzles type DUE-M are suitable for almost all
situations because of the wide range of variants available.
Because of their low height they are suitable for all types of space
and can be easily installed.
The multi-jet nozzles consist of spherical discharge nozzles fitted
into a plate complete with a face mounting flange, the plate can
either be curved or flat depending on whether the array is to be
fitted to a rectangular or circular duct, the linear nozzle array can
be in one or two rows.
Constructions · Dimensions
The multi jet nozzles type DUE-S-Q-M can be installed on a wall
or directly on the side of a rectangular duct, and consist of a flat
plate and jet nozzles in one or two rows.
The multi jet nozzles should be DUE-S, if they are to be with
angular adjustment or DUE-V with angular and rotational
adjustment.

Installation · Materials
Materials
TROX multi jet nozzles are suitable for installation on rectangular
or circular ducts.
The types DUE-S-QR-M, DUE-V-QR-M and DUE-S-RR-M are
used for installation into circular ducts.
The type DUE-S-RR-M is supplied with a predrilled plate and the
types DUE-S-QR-M and DUE-V-QR-M, are supplied with predrilled
flanges for screw fixing to the duct work. These types are suitable
for fitting to most commonly used circular duct diameters. On
the other hand, multi jet nozzles types DUE-S-Q-M and
DUE-V-Q-M are suitable for installation on rectangular duct work
or on a wall. For this reason, the face plate is supplied predrilled
for screw fixing. It is advised to fit a seal between the flange/plate
and the mounting surface.
The set is composed of a spherical casing, an inner piece of
nozzle, a face sheet and some duct connection flanges.
Spherical casing is made of aluminium. Face plate and duct
connection flanges are made of galvanized steel sheet, or
aluminium under request. The complete set is powder coated in
white (RAL 9010) or any other RAL colour under request.
Inner piece of the nozzle is made of plastic ABS V0 (black colour).
The set could also be provided by a perforated sheet steel plate
for flow rate control, power coated in black (RAL 9005).

If vH1 deviates from the specific value,
must be corrected upwards or downwards.
L and H1 are changed as a result.
Repeat the analysis.
αW is calculated: S = (H + y) / L
(αw from table 3)
Note: αW + αK = Max. 60º

Motorised adjustement of the discharge angle on a
change of supply air temperature is only possible up
to a max. αW + αK = 60º
∆ tL from diagram 4:
∆ tL = (∆ tL / ∆ tZ) · ∆ tZ
∆ tL = …K
Technical Data
Cold air
αk = 20º
L = A/C = 15/0,94 = 16,0 m. (C from table 1)
H2 = T · A = 0,36 · 15 = 5,4 m. (T from table 2)
from diagram 1: L = 0,91 m/s
from diagram 2: y = 0,9 m.
H1 = H + H2 – y = 5,8 + 5,4 - 0,9 = 10,3 m.
from diagram 3: H1 < 0,05 m/s
Example
Data given:
2 multi jet nozzles are to be fitted at a spacing of 30 m (A = 15 m)
and at a height of H = 4 m above the occupied zone, dischar ging
towards each other.
For cooling, for each nozzle
w = 100 l/s con ∆tw = +4 K.
k
= 200 l/s with ∆ tk =-8K and for heating
Warm air
data given: L = 0,45 m/s
from diagram 1: L = 14,5 m.
from diagram 2: y = 1,1 m.
S = (H + y)/L = (5,8 + 1,1)/14,5 = 0,48
from table 3: αw = 30º
from diagram 7:
with = 200 l/s
LWA = 43 dB(A)
∆pt = 155 Pa
with = 100 l/s
LWA = 23 dB(A)
∆pt = 38 Pa

Materials
Multi jet nozzles type DUE-M are used for preference where
the supply air from the diffuser has to travel a large distance
to a small occupied zone. They are suitable for long throw
distances with optimum acoustic properties, preferably
used for heating and cooling in critical areas. The manual
adjustment allows variation to compensate for changing
temperature differences. Adjustment angular range 30º
upwards to 30º downwards for construction S. It can also
be rotated through 360º with construction V. DUE-M jet
nozzles are recommended for circular, rectangular ducts or
for direct wall mounting.
The set is composed of a spherical casing, an inner piece
of nozzle, a face sheet and some duct connection flanges.
Spherical casing is made of aluminium. Face plate and duct
connection flanges are made of galvanized steel sheet, or
aluminium under request. The complete set is powder
coated in white (RAL 9010) or any other RAL colour under
request.
Inner piece of the nozzle is made of plastic ABS V0 (black
